<P><STRONG>Function</STRONG>
<P>
Gets the offset of a partition within the original Field after
partitioning.
<P><STRONG>Syntax</STRONG>
<BR>
<TT><STRONG><BR>
&#35;include &lt;dx/dx.h&gt;<BR>
<P><BR>
MeshArray DXGetMeshOffsets(MeshArray a, int *offsets)<BR>
</STRONG></TT><BR>
<P><STRONG>Functional Details</STRONG>
<P>
The offsets are specified as an Array of integers, one for each
dimension of the mesh, specifying the offset along that
dimension of the partition in the original Field.
In the case where a Mesh Array is used to define a regular grid of
connections that is a part of a partitioned Field, it is
useful to know the offset of the partition in
the original Field.
<P>
<TT><STRONG>DXGetMeshOffsets</STRONG></TT> works only on fully regular Mesh
Arrays (e.g., those that contain only Path Arrays).
Mesh Arrays containing any other type of array will cause an error.
In the event that this routine is passed to an Array that is not
the result of partitioning, zeros are returned.
<P><STRONG>Return Value</STRONG>
<P>
Returns <TT><STRONG>a</STRONG></TT> or returns <TT><STRONG>NULL</STRONG></TT>
and sets an error code.
